docs: link the Intent Layer AGENTS.md files and global invariants from CLAUDE.md

[satyamshivam13]

Summary

Adds an Intent Layer section to CLAUDE.md that points contributors at the three AGENTS.md files already tracked in the repo, and records the invariants that cut across them.

• Directs readers to src/analyzers/AGENTS.md, src/utils/AGENTS.md, and src/models/AGENTS.md before modifying code in those directories.
• Documents global invariants: the analyze() → AnalysisResult entry point, the get_settings() lru_cache singleton, lazy transformer imports that keep app.py runnable without torch, the Verdict.UNCERTAIN error-handling contract, and the Black/isort/flake8 style config.

Notes

Documentation only — no code changes, no behavior change.
